A stock Corvette exhaust system has sounds like a traditional American muscle car, with a throaty, throbbing rumble at idle and a deep roar under acceleration. The exact sound varies slightly by year, equipment package and wear on the system. The stock exhaust system is virtually silent inside the car.
Aftermarket Corvette exhaust systems, such as those manufactured by Corsa, Borla and B&B, alter the sound produced by the exhaust. All three tend to enhance the deep rumble, generating a louder, thicker sound, especially on acceleration and at speed. Systems such as these are designed to give even a stock Corvette engine an exhaust sound that mirrors race care output.
